Information

 
TitleA partition on a brand new VDX6740 fails to boot.
Symptoms
A partition on a brand new VDX6740 fails to boot.
In show version, only one partition, SW/0 or SW/1 appears.
Environment
  • VDX6740
  • All versions of NOS software including NOS 6.0.2h
Cause
Extreme performs extensive testing on each VDX6740 before shipment. After testing is complete, during the very last power down before packaging and shipping, there is an extremely small chance of file corruption. This file corruption can lead to a partition failing to boot. In the very first power up after unboxing, only one partition will appear in "show version".
Resolution
Immediate full recovery is possible with netinstall. For further details please refer to How to perform netinstall on VDX 6740,6940 and 8770 via USB?.

Optionally, to obtain further data about corrupted files prior to recovery, it is possible to collect a supportsave when only one partition is visible in "show version". Extreme Technical Assistance Center may be able to examine the output from the virtual management module running on the partition that did not boot in the supportsave from the partition that did boot.

Optionally, to view messages about corrupted files prior to recovery, it is possible to view the output of the virtual management module running on the partition not visible in "show version". Connected and logged in over the serial port, while "show version" shows only the partition SW/0 , press Ctrl+Shift+6 and then the 2 key. The letter "c" will be displayed on the serial console, and the serial console connection will be moved to SW/1. The serial console can be returned to SW/0 by pressing Ctrl+Shift+6 and then the 1 key. The letter "b" will be displayed on the serial console, and the serial console connection will be moved back to SW/0.
